Mastering Go - Second Edition

Using version v2.0.0

Once again, in order to use our Go modules, we will need to create a Go program, which is called useV2.go and contains the following Go code:

package main 
 
import ( 
    v "github.com/mactsouk/myModule/v2" 
) 
 
func main() { 
    v.Version() 
} 

We are going to use a Docker image. This is the most convenient way of playing with Go modules because we are starting with a clean Go installation:

$ docker run --rm -it golang:latest
root@191d84fc5571:/go# cd /tmp
root@191d84fc5571:/tmp# cat > useV2.go
package main
    
import (
    v "github.com/mactsouk/myModule/v2"
)
    
func main() {
    v.Version()
}
root@191d84fc5571:/tmp# export GO111MODULE=on
root@191d84fc5571:/tmp# go run useV2.go
